REGULATIONS
1. Preamble and objectives of the Course :
In the first two semesters of the six semester graduation program of
B. Sc.(Chemistry) the learner was introduced to some basic aspects in the
various core branches of chemistry like Physi cal Chemistry, Organic
chemistry and Inorganic chemistry. Concepts about the structure of atom,
distribution of electrons, Thermodynamics, Formation of organic
compounds and basic ideas in reactivity of molecules in general and
organic compounds in particu lar were introduced to the learner. He was
made inquisitive about why and how should atoms combine to give
molecules or ions. The non -orbital approach to appreciating the shapes of
polyatomic species in general and molecules in particular.
The story of che mistry is taken further in the coming two semesters
of the second year of the B. Sc. (Chemistry) Program. However it is also
realised that some students opting for the course on Chemistry may not
continue with the subject subsequently as such the syllabus is designed to
retain the interest of the serious learner of chemistry as well as be helpful
to non -chemistry learners. With such students who would want to pursue
other branches of science but would want to acquire a basic appreciation
and experience of c hemistry a separate paper (Paper -III) is designed. This
paper along with the laboratory session unit that goes with it deals with the
basics of chemical analysis, separating components from a given sample,
basic concepts like pH, experimental techniques li ke Titrimetry,
Gravimetry, using instruments to carry out analysis, the various techniques
like chromatography, electrophoresis, Instrumentation in general is felt to
be of interest to learners of various branches like physics, botany, zoology,
and microbi ology.
The major objectives of B.Sc. Chemistry course are
 To infuse in the learner a spirit of inquiry into the fundamental aspects
of the various core areas of Chemistry.

Page 8

 To make the learner proficient in analysing the various observations and
chemical p henomena presented to him during the course.
 To make the learner capable of solving problems in the various units of
this course
 To give the learner an opportunity to get hands on experience of the
various concepts and processes in the various branches of chemistry
 To impart various skills of handling chemicals, reagents, apparatus,
instruments and the care and safety aspects involved in such handling
 To make the learner capable of analyzing and interpreting results of the
experiments he conducts or perform s
 To make the learner capable of acquiring or pursuing a source of
livelihood like jobs in chemical industry
 To arouse the interest to pursue higher levels of learning in chemistry,

Paper III
Basics in analytical Chemistry
Theory: 45 Lectures

The Role of Analytical Chemistry in various fields including non-chemistry fields such as
Environmental Science, Pharmacy, Medicine, Life Sciences, Petrochemicals, Arts (like Painting)
Forensic sciences and so on can never be underesti mated. This course is expected to introduce the
learner to this interesting field of Analytical Chemistry.
It is expected to provide the learner an overview of this very important branch of chemistry. After
successful completion of this course the learner is expected to be familiar with the question of
what is analysis, why it is required and the methods, techniques, procedures and protocols that
may be used or required in the course of a given problem of analysis. The learner is also expected
to appreciate the role of an Analytical Chemist and a Chemical Analyst.
Correctness or acceptability of the results of a given analysis and how to deal with wrong or
erroneous results: when to reject them and when and how to retain them to be meaningful and/or
acceptab le are some other attributes expected as outcomes of learning this paper As such it is felt
that this paper will be a subject of choice and interest for learners preferring a specialization in
Chemistry as well as to those who may have interests in other s cience fields as Physics, Botany,
Zoology, Microbiology, Geochemistry and so on.

Goal:
To introduce the learner to an area of learning that is vital for the inherent nature of the subject
itself but also is important and irreplaceable irrespective of the long-term interest of specialization
or subject of interest of the learner.
